Description

Technical Field

[0001] The utility model belongs to the technical field of mining charging, and in particular relates to a mining charging device. Background Art

[0002] Ore refers to a mineral aggregate from which useful components can be extracted or which has certain properties that can be utilized. It can be divided into metallic minerals and non-metallic minerals. The unit content of useful components (elements or minerals) in an ore is called the ore grade. Precious metal ores such as gold and platinum are expressed in grams per ton, and other ores are often expressed in percentages. When transporting ore, a mining feeding device is required to transport and screen it.

[0003] After searching the Chinese patent "A mining feeding device with screening function", the announcement number is "CN220460949U". This patent drives the screening frame to rotate through the driving gear and the tooth block, and the rotating screening frame can perform centrifugal screening on the mineral material. At the same time, the screening frame will drive the screening mesh to rotate synchronously, and the support rods on the baffle plate at the edge of the screening mesh plate will move up and down on the surface of the supporting rail. The support rods will drive the screening mesh plate to vibrate up and down synchronously through the baffle plate to improve the screening effect. After the screening is completed, the large pieces of slag retained on the screening mesh plate will be automatically discharged through the discharge pipe, the receiving pipe and the diversion pipe, avoiding the need for manual cleaning.

[0004] However, when the device is used to screen ore raw materials of different types and different particle size distributions, the screening effect of the ore is not ideal. There are problems of high energy consumption and low screening efficiency in the screening process. It is inconvenient to adjust the screening device according to different raw materials, which reduces the processing efficiency and processing quality of the feeding device, and cannot achieve graded screening.

[0005] Therefore, in view of this, the utility model proposes a mining feeding device to solve the problems existing in the above-mentioned prior art. Utility Model Content
